目前我的活动中有标签，我可以轻松地在标签之间滑动。但这里有一个错误：我无法选择选项卡！
在这里，我在新标签上。如果我点击 upcomming 我会得到这个
我需要滑动才能看到即将发布的内容！为什么会这样？这是我的代码：
public class Taby extends SherlockFragmentActivity {

public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main1);
Fragment tabOneFragment = new TabOne();
Fragment tabTwoFragment = new TabTwo();
PagerAdapter mPagerAdapter = new PagerAdapter(
getSupportFragmentManager());
mPagerAdapter.addFragment(tabOneFragment);
mPagerAdapter.addFragment(tabTwoFragment);
mViewPager = (ViewPager) findViewById(R.id.pager);
mViewPager.setAdapter(mPagerAdapter);
mViewPager.setOffscreenPageLimit(2);
mViewPager.setCurrentItem(0);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
mViewPager
.setOnPageChangeListener(new ViewPager.SimpleOnPageChangeListener() {
@Override
public void onPageSelected(int position) {
getSupportActionBar().setSelectedNavigationItem(
position);
}
});
ActionBar ab = getSupportActionBar();
ab.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);
com.actionbarsherlock.app.ActionBar.Tab tab1 = ab
.newTab()
